London-based designer Paul Cocksedge[1] has transformed old vinyl records into ingenious low-tech amplifiers that give your smartphone’s volume a solid boost without the need for wires or electricity. This stylish pieces are made simply by heating and molding recycled 12” records into a sound-enhancing conic shape. Recently unveiled at London Design Festival 2011, [2]the ‘Change the Record’ will turn your smartphone’s tiny speakers into a sweet sound system you can use to share your favorite tunes with others.

We’ve shown you some original, low-tech smartphone amplifiers before, and they’ve taken various shapes using different kinds of materials like fast-growing bamboo[3], chunky wood[4] and even other repurposed musical instruments[5]. But we have to say we especially love ‘Change the Record’ for its unique retro aesthetic that pays homage to the old phonograph[6] record player. Cheers for their clever design, which mixes the old and the very new in a classy way with low carbon impact.
